The first US patent for CRISPR/Cas gene editing was awarded to Feng Zhang of the Broad Institute and MIT on April 15, 2014, however a second patent application was submitted seven months prior to Zhang’s by Jennifer Doudna of UC-Berkeley and Emmanuelle Charpentier of the Helmholtz Center for Infection Research in Germany. Both Doudna/Charpentier and Zhang had been working on CRISPR/Cas systems with the controversy over who owns the CRISPR/Cas Intellectual property stemming from the first date both groups published. Doudna was the first to demonstrate CRISPR/Cas systems ability to edit targeted DNA, however Zhang was the first to demonstrate that this technology can be used to edit human cells. Since both groups have set up competing companies the fight over who owns this intellectual property could continue in the courts for many years.

Scientists at the University of Pennsylvania have used an adeno-associated virus and CRISPR/Cas9 technology to correct a rare liver disease that results from a defect in the urea cycle. Interestingly, the researchers found that the treatment was more effective in newborn over adult mice. Further improvements of the efficiency of repaired DNA integration is needed before genetic treatments are available for humans. The original research can be found at http://www.nature.com/nbt/journal/vaop/ncurrent/full/nbt.3469.html.

Editas Medice is the latest CRISPR startup to go public and the first IPO in 2016. The IPO sold 5.9 million shares at $16 each, bringing in $94.4 million. Despite the promising IPO, the future of Editas may rest in the patent dispute currently playing out over CRISPR. Editas has licensed the technology from the Broad Institute, which is currently in a patent battle with UC-Berkley with the results from the dispute expected in 1-2 years.

The Human Fertilization and Embryology Authority in Britain have approved the use of CRISPR/Cas9 gene to edit viable human embryos. The approval is only for a single research group investigating embryonic development. Unlike in the US, in Britain all experiments using human embryos must be approved by the government, meaning this research will not lead to the routine editing of embryos.

Worldwide 600,000 individuals die from malaria each year. Currently the best defenses against malaria include destroying habitats where mosquitoes breed, the distribution of insect nets, and the spraying of insecticides. Recently CRISPR gene editing technology has been used to insert genes into the mosquito genome that imparts resistance to the malaria parasite. In addition scientist can also insert the CRISPR gene editing system needed to propagate these genes through an entire population. This technique, coined a “Gene Drive,” could be used to make entire populations of mosquitoes resistance to malaria thus eliminating human infection. This same technology could also be used to reverse herbicide resistance in weeds and antibiotic resistance in bacteria.
